UMBRELLA.

Speeication of Letters Patent.

Patented Oct. 6, 1914.

Application filed November 19, 1913. Serial No. 801,809.

T0 all whom it may concern Be it known that we, VAN DYKE CRUSER andAcoLri-i RosENBLUM, citizens of the United States, residing at Brooklyn,in the county of Kings and State of New York, have invented certain newand useful Improvements in Umbrellas, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements inumbrellas; the object being to provide the stick of the umbrella with ayielding stop adjacent the top notch thereof, in order to allow therunner to pass over the same when the umbrella is subjected to aneXtreme pressure, whereby the umbrella can be turned inside out withoutinjuring the saine, in any way.

Another and further object of the invention is to provide a yieldingstop arranged in the path of an extension formed on the runner; saidextension limiting the upward movement of the runner so as to preventthe stretchers and ribs from being broken when the umbrella is reversed.

We are aware that we are not the first in the art to provide an umbrellawhich is so constructed that the same may be reversed or turned insideout in order to prevent the same from being broken by the wind pressure.However, in constructions as heretofore employed, the stick was providedwith a coil spring in order to allow the runner to move under extremepressure and it has been found iii use, that an umbrella constructed inthis manner, has many disadvantages.

1We have found that by providing the stick with a bowed spring forming ayielding stop, that an umbrella can be constructed much cheaper and willhave many advantages over umbrellas of this character, now in use.

Other and further objects and advantages of the invention will behereinafter Set forth and the novel features thereof defined by theappended claim.

ln the drawings Figure l, is an elevation of the stick, ribs andstretchers, showing the runner and a portion of the stick in section;and Fig. 2, is a similar view, showing the runner moved over theyielding stop so as to allow the ribs and stretchers to be reversed insuch a manner that they will be prevented from becoming broken when theumbrella is turned inside out.

Like numerals of reference refer to like parts in the several figures ofthe drawing.

In the drawing, 1 indicates the stick which may be formed of theordinary construction, having a top notch 2 secured thereto in which arepivotally mounted, ribs 3 and it will be seen that the notch is soconstructed that the ribs are free to move in either direction in orderto allow the umbrella to be set in a stretched position or reversed, aswill be later described.

The stick is provided with a slot 4 spaced from the top notchcommunicating with a chamber 5 in which is mounted a bowed spring 6which extends out through the slot 4L and is adapted to be engaged bythe eX- tension 7 of a runner S slidably mounted upon the stick and heldin its upper position, by a catch 9. The ruimer 8 carries a notch l0 inwhich are pivotally mounted stretchers 1l which are connected to the rib3 in such a manner that they are free to swing in either direction so asto allow the ribs to turn as shown in Fig. Q, when the runner has passedover the stop formed by the bowed spring.

In Fig. 2, it will be seen that when the umbrella is reversed or turnedinside out, the extension 7 of the runner 8 engages the top notch 2 inorder to prevent the ribs and stretchers from becoming broken. vWhen theumbrella is moved into open position, the extension 7 of the ruimer S isengaged by the yielding stop so as to limit the movement thereof to suchan extent that the umbrella will be held in a stretched position by thecatch 9. When the umbrella is subjected to an extreme pressure, eitherby the movement of the runner past the yielding stop when raising thesame or by an eX- treme wind pressure upon the inside of the same, thestop will yield so as to allow the ruimer to pass over the saine untilit has engaged the top notch in which position, the ribs and stretcherswill be reversed.

From the foregoing description, it will be seen that we have provided anumbrella which is so constructed that when the same is subjected to anunusual pressure, it can be turned inside out or reversed, withoutinjury to the saine in the least and after it has been moved into thatposition by exerting a pressure upon the ribs from the outside, it canbe moved back into its proper position. It will also be seen in theconstruction of umbrella as disclosed, that the ribs and stretchers arefree to move upon their pivots in either direction and that after therunner has passed over the yielding Stop, it will be retarded frommoving in a reverse direction by the action of the ribs and stretohers,so fis to prevent the same from beeoming strained. As the runner passesover the yielding stop, the movement of the seme is retarded byfrietionel contziet therewith and the umbrella is allowed to be reversedWithout injuring the same, :is is the ease *ith other constructions nonTin use.

We claim:

ln an umlinellsi9 the combination With a stick having i Chamber 'formedtherein provided with :i slot, of ribs pivotally Carried by said stick,a runner slidzibly mounted upon Said stick having an extension,stretchere connecting said runner to seid ribs, and a bowed Springarranged Within said chomber free to expend at each end having a,portion extending out through Said Slot in the path of travel of saidrunner, forming :i rietional stop for Said runner.

In testimony whereof We affix our signutures in presence of' tivoWitnesses.
